Debian GNU/Hurd (hurd-i386)

The GNU Hurd is a totally new operating system being put together by the
GNU group. In fact, the GNU Hurd is the final component which makes it
possible to built an entirely GNU OS -- and Debian GNU/Hurd is going to
be one such (possibly even the first) GNU OS. The current project is
founded on the i386 architecture, but expect the others to follow soon.
